A density-fitting implementation of the density-based basis-set correction method

Andreas Heßelmann, Emmanuel Giner, Peter Reinhardt +3

This work reports an efficient density-fitting implementation of the density-based basis-set correction (DBBSC) method in the MOLPRO software. This method consists in correcting th…

Effective quantum electrodynamics: One-dimensional model of the relativistic hydrogen-like atom

Timothée Audinet, Julien Toulouse

We consider a one-dimensional effective quantum electrodynamics (QED) model of the relativistic hydrogen-like atom using delta-potential interactions. We discuss the general exact…

Basis-set correction based on density-functional theory: Linear-response formalism for excited-state energies

Diata Traore, Emmanuel Giner, Julien Toulouse

The basis-set correction method based on density-functional theory consists in correcting the energy calculated by a wave-function method with a given basis set by a density functi…

Semiclassical approximations of photoabsorption cross sections beyond the continuum threshold

Julien Toulouse

We develop semiclassical approximations for calculating photoabsorption cross sections beyond the continuum threshold in quantum many-body systems. These approximations use the ful…

Photoionization and core resonances from range-separated time-dependent density-functional theory for open-shell states: Example of the lithium atom

Julien Toulouse, Karno Schwinn, Felipe Zapata +3

We consider the calculations of photoionization spectra and core resonances of open-shell systems using range-separated time-dependent density-functional theory. Specifically, we u…

Systematic lowering of the scaling of Monte Carlo calculations by partitioning andsubsampling

Antoine Bienvenu, Jonas Feldt, Julien Toulouse +1

We propose to compute physical properties by Monte Carlo calculations using conditional expectation values. The latter are obtained on top of the usual Monte Carlo sampling by part…
